Application mreissue filed November 26,

This invention relates to machines for use in the manufacture of shoes.

An object of the invent-ion is to provide a machine by use of which the work of forming and shaping the toes of stitchdown shoes is greatly expedited and the cost of manufacture correspondingly reduced by providing devices for pressing the edge of the upper upon the edge of the sole and shaping the 19 upper properly for attachment to the sole.

Another object of the invention is to provide a machine having presser and shaping devices, in combination with means for pressing said devices upon the shoe parts to be affected thereby and at the same time automatically actuating said devices to shape the adjacent portions of the uppers of the shoes and to secure them to the sole.

Another object of the invention is to pro- .vide a machine embodying the mechanisms mentioned, in combination with heating means for heating said pressing and shaping devices to adhesively attach the upper to the sole.

ll, Other objects will appear from the following description, reference being made to the accompanying drawings, in which Fig. 1 is a front elevation of the machine embodying my invention.

a Fig. 2 is a side elevation.

Fig. 3 is a diagrammatic view of the heating device.

Fig. 4 is an enlarged plan view of the pressing and shaping devices.

Fig. 5 is a front elevation thereof.

Fig. 6 is a sectional View on the line 66 of Fig. 4.

Fig. 7 is a sectional view showing the means for supporting the movable jaws.

The operative mechanism of the machine is supported by an appropriate frame comprising standards 1 strengthened by cross connections 2, 3 and 4 and supporting a top plate or table 5.

The specific embodiment of the invention shown comprises units, each of which is constructed and arranged to operate upon the toes of a pair of shoes. The invention'may be varied in this respect and the operating mechanism may be constructed and designed to 1929. Serial No. 410,010.

operate upon the heel seats or other parts of the shoes and to perform the entire shaping of said heel seats or other parts and to effect adhesive attachment of the same to the sole.

Each unit of the machine includes a shaft 6 mounted for vertical reciprocation through a bearing, 7. The shafts 6 of the respective units may be independently operative as shown. The operating devices for each shaft include a lever 8 extending. through a slot 9 in the corresponding shaft 6 and having its front end pivoted to the cross connection 3 and its rear end connected by a link 10 with a treadle lever 11. By downward pressure upon the treadle lever 11 the corresponding shaft 6 will be moved downwardly in opposition to a raising and supporting springv 12- connected to the lever 8 by a link 13'. Thus it will be seen that the springs 12 raise the respective shafts 6 to and normally support them in their upper or starting positions, and that the treadles 11 are operative to lower the shafts 6 in opposition to the springs 12. Each of the shafts, (3 may be held in its down position in opposition to its spring 12 by a device provided for that. purpose. As shown, each treadle lever 11 has a lateral-projection 14 designed and adapted to engage with the teeth of a ratchet 15 when the lever 11' isdown. This is for the purpose of holding the presser and shaping devices pressed upon the shoes until the purpose of such operation has been completed.

The front or working side edge of the'table top 5 has a number of serrated plates 16 at-" The under side of the toe; extremities of the soles are placed upon the tached thereto.

plates 16 when the uppers are to be pressed to shape and attached to the soles. The ser rations on the plates 16 prevent the solo from slipping. Each of the shafts 6 supports one or more presser and shaping devices and, in the embodiment of the invention shown, each shaft 6supports a pair of such presser and shaping devices.

A plate 17 is detachably secured to the up-,

per end of each shaft 6 above the table top 5 and is movable with the shaft to which it is attached. The plates 17 are guided vertically and held from lateral oscillation by rods 18 extending upwardl from the table top into holes 19 in the p ate 17. Cams 20 are rigid with the rods 18 and face the sides and the inner ends of the plates 16. Pressin and shaping devices are su ported by the p ates 17, one or moreof such devices being provided for each of the plates 16. The plates 17 have recesses 21 to receive the toes of shoes for shaping the toe portion of the uppers during operation of the machine.

The under side of the plates 17 have grooves 22 receiving the outer edges of wipers 23, the two wipers of each pair being connected by pivots 24 at their inner ends permitting converging and spreading movements of the outer ends of the wipers. The wipers 23 have beveled inner edges'25, the beveled upper surfaces flaring upwardly and outwardly forming attenuated lower edges. When the shaft 6 is moved down by operation of its treadle 11 the inner end and the side edges of the wipers 23 operate against the cams 20 with the result that the cam 20 at the inner end pushes the wipers outwardly and the cams 20 at the sides push the wipers toward each other. This causes the edges 25 of the wipers to press the toe portion of the upper inwardly under and around the former, or last, and the edge portion of the upper upon the upper side of the projecting vmargin of the sole. Glue having been applied between the upper and the sole, the upper will be properly shaped and secured to the solo.

The machine may include heating devices to heat the shaper and presser. As shown conventionally an electric heater 26 is in connection witheach of the plates 17. This "heater is preferably a multiple stage resistance heater and is controlled by a multiple point switch 27 in order to obtain the different degrees of heat required for different purposes. -Thus the sha r or presser may be heated to different dfgrees in conformity with the requirements of the o rations. The resistance circuit is energized y leads 28 and 29, and there is interposed in thecircuit a light circuit controlling the light 30 indicating when the circuit is open or closed, it being understood that the lamp is lighted when the circuit is closed.

The wipers 23 are removable and interchangeable, and wipers for operating on' shoes of different sizes may readily be mounted in the machine.

This machine greatly facilitates and expedites the work for which it is intended, and

y use of the machine one operator can perform a great deal more work than has been possible by use of other machines now in general use.

The construction of the machine and the arrangement of the parts thereof may be varied within equivalent limits without deisms parture from the nature and principle of the invention as set forth in the appended claims.
